1.1 What is the IZAR CENTER?
The IZAR CENTER is an M-Bus level converter / repeater, which as “memory” variant can
also be used as M-Bus master. In addition to reading M-Bus devices automatically and
independently, the memory variant can also monitor the data read out and react to alarm
conditions. The meter data stored in the IZAR CENTER can also be cyclically uploaded to an
FTP server.
1.2 What is the M-Bus?
The M-Bus (Meter Bus) is an inexpensive bus system used for reading resource meters,
such as water meters, heat meters and electricity meters. The M-Bus was developed by
Prof. Ziegler at Paderborn University in cooperation with the companies Texas Instruments
and Techem. It has been adopted as the European standard for all meters except electricity
meters.

The variants without memory can be used for the following purposes:
•Direct reading of M-Bus devices via a PC/laptop
•As repeater for connecting more than 250 M-Bus devices to an M-Bus network
or if the M-Bus lines are to bridge large distances (several kilometers)
The variants with memory offer the option of reading M-Bus devices automatically at
adjustable intervals, storing the data and sending this data over the interfaces on request.
The collected data can also be automatically uploaded to an FTP server. The IZAR CENTER
must be connected via the LAN interface or a special GPRS modem for this purpose.
An IZAR CENTER with memory can also monitor the M-Bus devices during automatic
reading and send an alarm report and/or alarm action in the event of an error.

2 Installation
2.1 Power supply
The IZAR CENTER is equipped with a universal power supply and can be operated with
mains voltages of 110 – 230 V AC (50..60 Hz).
2.2 M-Bus
2.2.1 M-Bus output
These terminals can be used to connect one or more pairs of wires to M-Bus devices. A
standard telecommunications cable can be used as M-Bus cable. The connection is not
polarity conscious. The maximum number of M-Bus devices that can be connected to an
IZAR CENTER depends on the type of IZAR CENTER used. See Table 1-1
The following types of connection are permitted:
•Star topology
•Bus topology
•Combination of bus and star topology
2.2.2 M-Bus input (Slave-In)
The M-Bus input is only intended for an IZAR CENTER without memory. An M-Bus signal
source (e.g. another IZAR CENTER or IZAR CENTER Memory) can be connected to this
input. All signals at this input to the IZAR CENTER are passed direct to the M-Bus output at
the same speed.
This makes it possible to connect several IZAR CENTERs in succession for reading more
than 250 M-Bus devices or if the M-Bus cable network contains excessively long lines.
Connecting several IZAR CENTERs in succession is called a cascade connection. A
cascade connection enables an M-Bus network to be expanded to any desired size.

Fig. 2-1 M-Bus cascade connection
Please note: Only one IZAR CENTER Memory can be used in a cascade connection. This
must then be placed at the start of the signal chain (see Fig. 2-1 M-Bus cascade connection
2.3 USB
The IZAR CENTER has a USB interface (USB B-socket) on the bottom side of the device for
direct connection to a PC/laptop. It is not necessary to install a special driver before
connecting.
Please note:
If you use Windows XP, you must remove the USB connector after the PC has recognized
the device and then reinsert the connector (this is only necessary once).
2.4 LAN
The LAN connection (RJ-45 socket) is located on the top side of the IZAR CENTER.
Use this connection if you want to read out the IZAR CENTER via TCP/IP. In addition to
direct reading/ configuration of the IZAR CENTER and the M-Bus devices, the IZAR
CENTER can automatically export data to an FTP server and send e-mails as alarm
messages.
The LAN connection supports dynamic IP address allocation (DHCP) and can also be
configured with a static IP address. Use the IZAR CENTER software for configuration of
these settings.
DHCP is activated by default. This means that the IZAR CENTER automatically attempts to
get an IP address. In this case, it is not clear which IP address the IZAR CENTER has been
assigned by the IT system. If you wish to find your device in the PC network, you can use the
TCP/IP search in the IZAR@CENTER software.
It is naturally also possible to connect the IZAR CENTER direct to the PC via a LAN cable,
but suitable static IP addresses must be assigned to the PC and the IZAR CENTER for this
purpose.
Please note: Connect the LAN connection of the IZAR CENTER before inserting the mains
plug.

2.5 Serial
The serial (RS232) interface can be used either for the direct connection of a PC or for
connecting a modem. The two functions cannot be used at the same time. Use the IZAR
CENTER software for setting the use of the serial interface.
2.5.1 RS232 – PC
If the serial interface is set to “PC” mode, you can connect the IZAR CENTER direct to a PC.
You do not need to install a driver on the PC.
Interface speeds (baud rates) of 300…57600 bauds can be used for communication with the
IZAR CENTER.
Baud rates of 300…9600 bauds can be used for communication with M-Bus devices.
Please note: At baud rates > 9600 bauds, communication signals are not passed through to
the M-Bus outputs (no communication with M-Bus devices).
The IZAR CENTER automatically detects the baud rate used (setting is not necessary).
2.5.2 RS232 – modem
If the serial interface is set to “Modem” mode, you can connect a modem to the IZAR
CENTER.
You can use the following types of modem:
•Analogue modem
•GSM modem
•GPRS modem
Attention: To ensure full and reliable operation, please use only modems specified by
HYDROMETER (see Suitable types of modem). No support is available for other types/models of
modem.

3 Configuration
3.1 Principles
3.1.1 Basic operation/architecture
As already mentioned above, an IZAR CENTER without memory serves only as a level
converter /repeater. The operation of this type is therefore relatively simple compared with
the IZAR CENTER Memory. As an IZAR CENTER Memory is equipped with functions like
automatic reading of M-Bus devices and parameter monitoring/alarm handling, it works with
internal lists. The following figure shows the architecture:
